SetViewPortAsync()

void Spices::Renderer::RenderBehaveBuilder::SetViewPortAsync

(

)

const

DynamicState Set Viewport and Scissor Async.

Use Negative Viewport height filp here to handle axis difference. Remember enable device extension (VK_KHR_MAINTENANCE1)

Though we draw world to viewport but not surface, Set Correct viewport here is necessary.

Instance a VkRect2D

Set VkViewport with viewport slate.

Set VkRect2D.
